At present, efficient pulverized coal fired industrial boiler, uses coal power ground by high quality coal dust, featuring the highest thermal efficiency and maximum energy-saving. So the boiler is the first extension project of 'Opinions on the Implementation for top 10 major Energy-saving Projects of 11th Five-year Plan of the State'.

    Emission of SO2:It can meet the requirements of the local regulations on environmental protection.
    Emission of Nox:≤400mg/m3
  • Technical Index
    Material coal shall be entered into the cryogenic grinding roll to be ground and sorted, after it is dried up to less than 5 per cent by rotary drying kiln, the quality index is the following:
    Qnef:≥4500kcal/kg
    Vdaf:≥25%
    Mmf:≤5%
    Aad:≤25%
    Percent passing of sieve mesh number of 200:>95%
Combustion Methods
Efficient pulverized coal-fired boiler system consists mainly of the following equipments: which are braise storage-supply subsystem, burner subsystem, measurment and control subsystem, boiler subsystem, bag-type dust remover subsystem, heating power subsystem, and other equipments, etc. The coal dust, which conformity with quality, shall be ran into coal dust tower by the closed tank wagon from coal dust factory. After it is put in measuring midbin as required, the braise in tower shall be sent to the pulverized coal burner by the feeder and the wind-power mixing tube. Firing system is constructed by burner and boiler furnace. After radiation and heat convection, high-temperature fume, produced in combustion process, shall enter the bag-type dust remover. Clean fume, expelled by bag-type dust remover, is blowned into atmosphere by the induced draft fan, and fly ash, collected by bag-type dust remover, is expelled by closed system, which shall be centralized disposed and used. The operation of boiler system is completed by ignition sequencer and superordination computer system in common.
